You have a solution of KNO3 containing 28 g KNO3 in 100 g H2O at 30 degree C. Is the solution saturated or unsaturated? How many phases will be present in the solution? If saturated how much salute remains undissolved? (Help)

Answer:

We have no data...

Explanation:

Nitrates TEND to be soluble species...

And here we gots a concentration of ....

#((28*g)/(101.10*g*mol^-1))/(100*mLxx10^-3*L*mL^-1)=2.77*mol*L^-1#.

This site reports prodigious solubility....i.e. #360*g*L^-1# at #20# #""^@C#...and it would be higher at #30# #""^@C#. And so, on this basis this solution is #"UNSATURATED"# with respect to potassium nitrate: i.e. the solution contains an amount of solute LESS than that amount which would be in equilibrium with undissolved solute.
